Abstract

An engine speed controlling apparatus for an internal com­ bustion engine (10) for controlling the engine speed of an internal combustion engine which has a means (16, 18) for governing the engine speed and in which a manipulated va­ riable of said governing beans and torque are in non-linear relationships. Although a real manipulated variable and the torque are in non-linear relationships, a virtual manipula­ ted variable in which an actual engine speed becomes a tar­ geted engine speed is calculated assuming those relation­ ships as being linear. The virtual manipulated variable is converted (by 38) to the real manipulated variable by using the actual non-linear relationships between the real mani­ pulated variable and the torque, and the governor is con­ trolled (by 40) on the basis of the converted real manipu­ lated variable.
